Now scientists have discovered that the dogs behave like their masters, too. Just like children, they use a “ look and learn” ways when they go about their tasks.
Scientists at Oxford universities designed an experiment to test if the dogs have the ability to copy humans' actions by using a simple wooden box. 10 owners showed their dogs how to open the wooden box .Sometimes they use their heads to push it and sometimes they use their hands.
10 dogs were divided into two groups—Group 1 and Group 2. In the first part of the test, Group 1 were rewarded with a piece of meat for copying their owner's actions. Group 2 were rewarded with food for not copying and using other ways. With each dog the experiment was repeated hundreds of times. Scientists recorded the time to see which group was first to get 85% right. They found that Group1finished the task much sooner than Group 2.
In the second part of the test, all the dogs were only rewarded for copying the way that their owners used. Group1 reached the 85% mark more quickly than Group 2.
So the scientists draw a conclusion: “Like humans, dogs can copy actions that they see. Dogs' imitative(仿效的)behavior is shaped more by their interactions(互动)with humans than by evolution(进化).”
Scientists said,“A dog's behavior is influenced much like that of a child; they look and learn similar behavior. We hope that owners understand the importance of their actions and use this knowledge to set good examples and therefore have a good effect on the behavior of their pets.”

(1)、The scientists believe dog's imitative behavior mainly comes from______________.

A、proper rewards B、domestication C、human-dog interactions D、evolution
(2)、The best title may be “___________________”.

A、Dogs can finish their tasks quickly B、Dogs are interesting animals C、Masters always set good examples D、Dogs behave like their masters.
(3)、From the experiment, we know _______________.

A、It took the two groups of dogs the same time to finish the required task B、The dogs that copied their masters finished the required task much sooner C、The dogs that were encouraged to copy their masters finished the task more slowly D、The dogs that were encouraged not to copy their masters finished the task more quickly
(4)、According to the last paragraph, we can infer ______________.

A、a cruel man can raise a cruel dog B、dogs can be influenced by anyone C、dogs always behave positively D、dogs are the best kind of pets

Why does the sky change colors?

    What is the sky? How high is it? What color is it? What birds can live above it? These questions are difficult to answer, aren't they?

    In fact, the sky has no color. Then why does the sky look blue?

    We know that there is air around the world. When planes fly, they need air to lift their wings. Planes can't fly very high. That is because the air gets thinner when they go higher. The same will happen to us if we go high enough. If we go up about 1, 200 kilometers from the earth, we'll find no air there. Some birds can fly into the sky as high as a plane, but they cannot fly or live without air.

    Looking up above us, you will see the blue sky with white clouds. It is usually light blue. The color would be bluer when you see on the top of a high mountain. And you will see fewer clouds in the sky between you and the sun.

    Sometimes the sky doesn't look blue. When the sun rises and falls, you will see red, orange, and other colors in the sky. Such are the most beautiful moments of the day.

    Who can see the colors of the sky high above the earth? The astronauts! They can see those beautiful colors of the sky from the outer space. However, before flying into outer space, they sit in a spaceship high above the earth, and there is no air at all. The sky would be that dark and its color would be black.

    Now you may understand that we see colors because the air scatters(使散射) the sunlight. light travels through the air. Without air, there would be no light or colors.
